[reaction: see text] The ruthenium porphyrin-catalyzed reactions of diazo ketones with pi-unsaturated compounds via carbonylylide formation/cycloaddition cascade exhibit product yields and selectivities comparable to the analogous reactions with dirhodium carboxylates as catalysts. By grafting a ruthenium porphyrin on poly(ethylene glycol) (Zhang, J.-L.; Che, C.-M. Org. Lett. 2002, 4, 1911), a recyclable
